limit the number of points in SkDashPathEffect::asPoints

If the length of a line path is sufficiently long relative to the dash
interval, it is possible to cause SkDashPathEffect::asPoints to produce
so many points that it overflows the amount that can fit in an int type,
or otherwise produce non-finite values, i.e. path from (0,0) to (0,9e15)
with a dash interval of 1.

This fixes that by capping the amount of points to a sane limit - in this
case, 1mil, since that limit is also used in utils/SkDashPath.cpp and has
precedent.

Correct sRGB <-> linear everywhere.

This trims the SkPM4fPriv methods down to just foolproof methods.
(Anything trying to build these itself is probably wrong.)

Things like Sk4f srgb_to_linear(Sk4f) can't really exist anymore,
at least not efficiently, so this refactor is somewhat more invasive
than you might think.  Generally this means things using to_4f() are
also making a misstep... that's gone too.

It also does not make sense to try to play games with linear floats
with 255 bias any more.  That hack can't work with real sRGB coding.

Rather than update them, I've removed a couple of L32 xfermode fast
paths.  I'd even rather drop it entirely...

Fix context creation problems in dm

Fixes these issues:

1. The glXCreateContextAttribsARB call seems to modify the
context_attrib parameter upon failure. Since context_attrib was static,
if it first tried to create an OpenGL 4.4 context and it failed, further
attempts to create a context with lower versions would also fail.

2. Getting an OpenGL 3.0 context was never tried.

3. Context creation for ES 3.0 was failing on my machine. Since ES 2.0
looks like the intended version from the surrounding code, I set it to
that. It could be rewritten to use a similar loop as standard OpenGL and
try from the highest version to the lowest.

Introduce GrColorSpaceXform, for gamut conversion on textures

GrTextureAccess optionally includes an instance, computed from the src
and dst color spaces. In all common cases (no color space for either src
or dst, or same color space for both), no object is allocated.

This change is orthogonal to my attempts to get color space attached to
render targets - regardless of how we choose to do that, this will give
us the source color space at all points where we are connecting src to
dst.

There are many dangling injection points where I've been inserting
nullptr, but I have a record of all of them. Additionally, there are now
three places (the most common simple paths for bitmap/image rendering)
where things are plumbed enough that I expect to have access to the dst
color space (all marked with XFORMTODO).

In addition to getting the dst color space, I need to inject shader code
and uniform uploading for appendTextureLookup and friends.

pathops coincidence and security rewrite

Most changes stem from working on an examples bracketed
by #if DEBUG_UNDER_DEVELOPMENT  // tiger
These exposed many problems with coincident curves,
as well as errors throughout the code.

Fixing these errors also fixed a number of fuzzer-inspired
bug reports.

* Line/Curve Intersections
Check to see if the end of the line nearly intersects
the curve. This was a FIXME in the old code.

* Performance
Use a central chunk allocator.
Plumb the allocator into the global variable state
so that it can be shared. (Note that 'SkGlobalState'
is allocated on the stack and is visible to children
functions but not other threads.)

* Refactor
Let SkOpAngle grow up from a structure to a class.
Let SkCoincidentSpans grow up from a structure to a class.
Rename enum Alias to AliasMatch.

* Coincidence Rewrite
Add more debugging to coincidence detection.
Parallel debugging routines have read-only logic to report
the current coincidence state so that steps through the
logic can expose whether things got better or worse.

More functions can error-out and cause the pathops
engine to non-destructively exit.

* Accuracy
Remove code that adjusted point locations. Instead,
offset the curve part so that sorted curves all use
the same origin.
Reduce the size (and influence) of magic numbers.

* Testing
The debug suite with verify and the full release suite
./out/Debug/pathops_unittest -v -V
./out/Release/pathops_unittest -v -V -x
expose one error. That error is captured as cubics_d3.
This error exists in the checked in code as well.
